Grammy Stars Warned: Cover Up Your Body Parts

In an unusually frank email to attendees of this Sunday's music-awards show, CBS has identified – rather bluntly – exactly which body parts it doesn't want to see exposed by those swanky designer outfits.

"Please be sure that buttocks and female breasts are adequately covered," reads the email, obtained by Deadline.com. "Thong type costumes are problematic. Please avoid exposing bare fleshy under curves of the buttocks and buttock crack. Bare sides or under curvature of the breasts is also problematic."

The missive continues: "Please avoid sheer see-through clothing that could possibly expose female breast nipples. Please be sure the genital region is adequately covered so that there is no visible 'puffy' bare skin exposure."
